Abstract
This paper presents a newly developed numerical model to simulate interfacial multi-phase flows with high density ratio such as the water and air mixing flows in sanitary wares. In order to adequately resolve thin water films on the curved surfaces of the sanitary ware products, the VSIAM3 (Volume-integrated average and Surface-integrated average Multi-Moment) and STAA (Surface Tracking by Artificial Anti-diffusion) methods have been extended to arbitrary unstructured grids, which enables the numerical model to simulate interfacial multiphase flows in complex geometric configurations with significantly improved accuracy. Moreover, the algorithmic simplicity of the numerical framework eases the implementation of high performance computing using Graphic Processor Unit (GPU) acceleration technique and Message Passing Interface (MPI) parallel computing. Satisfactory results have been achieved in the benchmark verifications and the real-case validation of a sanitary ware product.
